Based on the Impact Echo Principle
Meets ASTM Standard C1383-04(10)

 

 

Concrete Thickness Gauge

The CTG-2 is a hand-held, battery powered, nondestructive system for measuring the thickness and integrity of concrete slabs, pavements, tunnel linings, walls and other plate-like structures using the Impact Echo principle. Requires no special knowledge or trainingconnect the CTG-2 to your laptop or tablet* and start testing with Olson’s WinCTG2 software. For greater accuracy, calibrate the unit at a location of known thickness to obtain the concrete velocity for that job.

*To test concrete and acquire data, the CTG-2
system must be used with a Windows 7/Windows
8 computer or tablet running Olson Instrument’s
WinCTG2 software. The required computer or
tablet 
must be provided by the user.
